Linn Area Credit Union, founded in 1935 by 11 Cedar Rapids teachers as Cedar Rapids Teachers' Credit Union, grew into a full-service cooperative serving 22 counties in Eastern Iowa. In May 2024 it rebranded as Corda Credit Union. It offers checking, savings, auto loans, and mortgages to residents across its expanded Eastern Iowa membership area.

Linn Area Credit Union has been part of the Cedar Rapids community since 1935, when eleven local teachers pooled just $5 each to start a credit union for their coworkers. Today, operating as Corda Credit Union after a 2024 rebrand, it serves members across a 22-county stretch of Eastern Iowa with everyday checking, savings, auto loans, and mortgages. Wherever you bank, you can use the Fluz app to earn cashback and rewards when you make purchases or loan payments tied to your credit union account, so your everyday banking works a little harder for you.
